Skins unavailable?

I’m confused. I downloaded 2.0 and I see the skins in the .zip file but when I go to the design option in admin, the drop-down menu doesn’t show but 5 or 6 skins. A lot of the cool ones on the cscart website like Solitude aren’t available. I been searching the forum and can’t figure this out.

A lot of the coolest skins started to come in 2.0.7. not sure what is included in the demo
